5A Bipolar Linear Regulator

Shanghai Belling Co., Ltd. 

BL1084

DESCRIPTION

BL1084 is a series of low dropout three

terminal regulators with a typical dropout

voltage of 1.4V at 5A load current.

Other than fixed voltage versions (1.8V, 2.5V,

3.3V, 5.0V), BL1084 has an adjustable

voltage version, with which desired voltage

can be achieved by setting the values of two

external resistors of the application circuitry.

BL1084 offers thermal shut down and current

limit functions to assure the stability of chip

and power system.

BL1084 series is available in standard

packages of TO-263-2L, TO-263-3L, TO-220

and TO-252.
